This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "L'intégration des sources d'énergie renouvelables (SER) est une question délicate pour le réseau électrique. Il est possible de produire de grandes quantités d'électricité à partir de ces sources, mais de manière intermittente et plutôt imprévisible. En outre, la plupart des énergies renouvelables sont intégrées à des niveaux de tension moyens ou bas. De nouveaux réseaux, appelés microréseau (MR), ont été introduits comme une solution pertinente pour intégrer les générateurs renouvelables avec de nouveaux dispositifs issus de l'électronique de puissance et de nouvelles approches de contrôle avancées. En effet, la question cruciale est de savoir comment l'intégration et l'interconnexion des sources d'énergie renouvelables peuvent être effectuées sans affecter la sécurité, la stabilité et la fiabilité du microréseau. Avec un temps de réponse de l'ordre de quelques millisecondes, le Ressort Électrique (ES) a récemment été introduit comme une technologie efficace pour traiter divers problèmes de stabilisation et de qualité de l'énergie, notamment l'instabilité des tensions aux différents jeux de barres, la répartition de la puissance et le déséquilibre de l'énergie. Cette thèse concerne la conception, la modélisation et le contrôle d'un microréseau CC pour intégrer différentes sources renouvelables, y compris la récupération de l'énergie solaire et de l'énergie éolienne, le stockage d'énergie dans des batteries ou supercondensateurs et l'alimentation des charges, pour un bon fonctionnement et une stabilité fiable. La stabilisation de la tension du jeu de barres CC est assurée par un stabilisateur électronique de type ES commandé par une stratégie de contrôle non linéaire, où une étude de la stabilité est rigoureusement réalisée. Dans ce travail, la méthode non linéaire par mode glissant à action intégrale ISMC a été proposée en adoptant la fonction de Lyapunov dans la conception de la loi de commande pour contrôler le ES et pour assurer la stabilité de l'ensemble du système. Différents scénarios de variations de la puissance produite et consommée et des variations des paramètres ont été effectués et testés pour analyser le comportement dynamique et la robustesse du stabilisateur. L'analyse de la stabilité a confirmé que le système fonctionne correctement dans la région de stabilité, et d'après les résultats, l'insertion du stabilisateur ES a mené à de bonnes performances de robustesse. Les simulations, effectuées dans l'environnement Matlab/Simulink, ont permis de mettent en évidence les meilleures performances de la stratégie de contrôle proposée, sa robustesse dynamique et paramétrique en comparaison avec celles obtenues en utilisant le contrôleur linéaire traditionnel (PI). Mots-clés : Énergie renouvelable, microréseau, ressort électrique, commande robuste par mode glissantintégral, stabilité, performance."--Résumé.

Book excerpt: Les énergies renouvelables, fournies par le soleil, l'eau, le vent, la terre, les végétaux... par opposition aux énergies fossiles, sont inépuisables et n'engendrent pas ou peu de déchets et d'émissions polluantes. Dès 2012, tous les bâtiments construits en France devront répondre aux normes de basse consommation en intégrant systématiquement les énergies renouvelables les plus performantes. Il est donc important de réfléchir dès maintenant au recours à ce type d'énergie. Du besoin à l'exploitation, ce guide analyse dans le détail les points suivants : Quel est le contexte législatif et réglementaire national et européen ? Quels sont les systèmes utilisant les énergies renouvelables et leurs caractéristiques? Systèmes solaires thermiques ; Systèmes solaires photovoltaïques ; Systèmes de chauffage au bois ou à biomasse ; Systèmes éoliens ; Raccordements à des réseaux de chauffage ou de refroidissement collectifs à plusieurs bâtiments ou urbains ; Pompes à chaleur géothermiques ; Autres types de pompes à chaleur ; Chaudières à condensation ; Systèmes de production combinée de chaleur et d'électricité. Comment réaliser l'étude de faisabilité réglementaire ? Comment intégrer ces systèmes dans le cadre bâti ? Quelles sont les chaînes d'acteurs en jeu ? Le guide détaille aussi les modes de financement possibles, l'économie des projets en termes de coût global et les formes de contrats envisageables. Les professionnels (maîtres d'ouvrage publics et privés, entreprises de construction, architectes, bureaux d'études, assistance à maîtrise d'ouvrage, gestionnaires de patrimoine...) trouveront dans ce guide les réponses à toutes les questions qu'ils se posent face aux choix énergétiques qu'ils ont à faire et aux conséquences de ces choix.

Download or read book Eskom written by Sylvy Jaglin and published by Juta and Company (Pty) Ltd. This book was released on 2016-08-16 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa’s leading producer of electricity, Eskom Holdings SOC Ltd, is also a vertically integrated monopoly, owned by the South African state. This national champion was shaken in 2008, when it was obliged to introduce ‘load shedding’, or rolling blackouts, and again in late 2014. Trying to understand how and why one of the iconic pillars of South African state capitalism is now in distress, the authors of this book argue that the so-called electricity crisis is in fact a public monopoly crisis. Moving beyond technical aspects, they explore the relationship between state power and Eskom before, during and after apartheid. From this perspective, they suggest that the current technical and financial troubles of this public utility are illustrative of the weakening of its technopolitical regime, of how national institutions have governed Eskom’s technological development, and of the pursuit of political goals in the production of electrical power. Without a clear industrial strategy during the 2000s, Eskom became a powerful tool of Broad-Black Economic Empowerment as well as a neopatrimonial system which generates profits captured by the ruling party. As a result, crisis in Eskom shakes the whole political edifice. Inefficient and its finances increasingly under scrutiny, this state-owned enterprise’s existence as a monopolistic public utility is regularly a subject of debate. The authors discuss the ambivalent role of Eskom in the national energy transition policy and whether solutions point in the direction of de-integrating this public monopoly and allowing its current technopolitical regime to enter a planned or natural decline.
Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Book Synopsis Energy Justice in a Changing Climate by : Karen Bickerstaff
Download or read book Energy Justice in a Changing Climate written by Karen Bickerstaff and published by Zed Books Ltd.. This book was released on 2013-10-10 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy justice is one of the most critical, and yet least developed, concepts associated with sustainability. Much has been written about the sustainability of low-carbon energy systems and policies - with an emphasis on environmental, economic and geopolitical issues. However, less attention has been directed at the social and equity implications of these dynamic relations between energy and low-carbon objectives - the complexity of injustice associated with whole energy systems (from extractive industries, through to consumption and waste) that transcend national boundaries and the social, political-economic and material processes driving the experience of energy injustice and vulnerability. Drawing on a substantial body of original research from an international collaboration of experts this unique collection addresses energy poverty, just innovation, aesthetic justice and the justice implications of low-carbon energy systems and technologies. The book offers new thinking on how interactions between climate change, energy policy, and equity and social justice can be understood and develops a critical agenda for energy justice research.

Book Synopsis Contemporary Criminological Issues by : Carolyn Côté-Lussier
Download or read book Contemporary Criminological Issues written by Carolyn Côté-Lussier and published by University of Ottawa Press. This book was released on 2020-05-05 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary Criminological Issues tackles some of today’s most pressing social issues, from the criminalization of Indigenous peoples to interpersonal violence, border control, and armed conflicts. This book advances cutting-edge theories and methods, with the aim of moving beyond the scholarship that reproduces insecurity and exclusion. The breadth of approaches encompasses much of the current critical criminological scholarship, serving as a counterpoint to the growth of managerial and administrative criminologies and the rise of explicitly exclusionary and punitive state policies and practices with respect to ‘crime’ and ‘security.’ This edited collection featuring two books, one in English and one in French, includes important contributions to knowledge and public policy by eminent experts and emerging scholars. This book is published in English.
Book Synopsis Arctic Shipping by : Frédéric Lasserre
Download or read book Arctic Shipping written by Frédéric Lasserre and published by Routledge. This book was released on 2019-09-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.
Download or read book Managing Complexity written by G. Rzevski and published by WIT Press. This book was released on 2014-03-25 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Managing Complexity is the first book that clearly defines the concept of Complexity, explains how Complexity can be measured and tuned, and describes the seven key features of Complex Systems: ConnectivityAutonomyEmergencyNonequilibriumNon-linearitySelf-organisationCo-evolution The thesis of the book is that complexity of the environment in which we work and live offers new opportunities and that the best strategy for surviving and prospering under conditions of complexity is to develop adaptability to perpetually changing conditions. An effective method for designing adaptability into business processes using multi-agent technology is presented and illustrated by several extensive examples, including adaptive, real-time scheduling of taxis, see-going tankers, road transport, supply chains, railway trains, production processes and swarms of small space satellites. Additional case studies include adaptive servicing of the International Space Station; adaptive processing of design changes of large structures such as wings of the largest airliner in the world; dynamic data mining, knowledge discovery and distributed semantic processing. Finally, the book provides a foretaste of the next generation of complex issues, notably, The Internet of Things, Smart Cities, Digital Enterprises and Smart Logistics.

The last chapters are devoted to non-equilibrium processes and to kinetic equations, with many applications included.
Book Synopsis Four Laws That Drive the Universe by : Peter Atkins
Download or read book Four Laws That Drive the Universe written by Peter Atkins and published by OUP Oxford. This book was released on 2007-09-06 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal, and from the unfurling of a leaf to the course of life itself - everything is directed and constrained by four simple laws. They establish fundamental concepts such as temperature and heat, and reveal the arrow of time and even the nature of energy itself. Peter Atkins' powerful and compelling introduction explains what the laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader from the Zeroth Law to the Third Law, he introduces the fascinating concept of entropy, and how it not only explains why your desk tends to get messier, but also how its unstoppable rise constitutes the engine of the universe.
Book Synopsis Multi-party Elections in Africa by : Michael Cowen
Download or read book Multi-party Elections in Africa written by Michael Cowen and published by . This book was released on 2002 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains electoral studies of multiparty politics in 14 African countries during the 1990s. Most are about national elections in Anglophone Africa. There are also less well-known examples from Sudan, Ethiopia and Guinea Bissau. The collection also features studies of the local elections in Namibia and of a significant by-election in Malawi. The multiparty period had been put, wherever possible, within the historical context of earlier elections in Africa. Questions addressed include: how did incumbent governing regimes learn to live with multiparty politics? Why have some elections been so closely fought and others have suffered from apathy? Why has there been relatively open political expression and activity when the elections have increased the political and economic manipulation by incumbent governments? Why have the elections of the 1990s been so marked by local and ethnic variations? To what extent did this wave of democracy result from pressure from donor countries?
